On the show, Lamar is still recovering in a Los Angeles hospital and Khloe's been visiting him constantly.
During a rare moment back at her house, Khloe talked to her sisters Kim Kardashian and Kourtney Kardashian about Lamar's condition and confessed that she "feels so guilty" when she leaves him at the hospital.
What else did Khloe reveal about Lamar?
1. Khloe Gives an Update on Lamar:
Khloe, Kim and Kourtney are spending time together when Khloe opens up about Lamar.
"Kobe (Bryant) did physical therapy with him yesterday it was really cute," Khloe says.
"Does he remember Kobe, like does he know?" Kim asks.
Khloe reveals, "I said I go, 'Did you have a nice morning with Kobe?' He said, 'Intense.'"
She goes on to explain, "The situation right now is incredibly fragile, hospital life is not fun and it's depressing and sad and I'm very protective over Lamar right now. I feel so guilty being away from him, even though I have technically left the hospital, my brain is still at the hospital. I get super anxious."
Khloe then tells Khloe and Kim that an employee asked Lamar for a photo at the Las Vegas hospital.
"I was talking to the nurse and I said, 'An employee at the Las Vegas hospital asked Lamar the day he woke up out of a coma if he could take a picture with him,'" Khloe explains.
2. Kim Spills a Secret About Kendall Jenner:
Kendall Jenner finds out she's been selected to walk in the Victoria's Secret Fashion Show, but it's supposed to be a secret. Only a select number of people know about Kendall's casting, but Kim tells Caitlyn Jenner during her birthday lunch.
"You should go to the Victoria's Secret Show," Kim tells Caitlyn. "Kendall's walking, it's a huge surprise and it's a really big deal."
A shocked Caitlyn asks, "She's walking in Victoria's Secret?"
"It's a surprise," Kylie says.
"It's a secret but you should go," Kim explains.
"Oh I should go you're absolutely right," Caitlyn says.
"You and Kylie should go together," Kim says. "Don't say anything."
3. Kourtney Visits Scott Disick in Rehab:
"How was it when you went to see Scott?" Kim asks.
"It was good," Kourtney says. "I was happy to go."
"Yeah I'm glad you went," Kim tells her.
Kourtney goes on to explain, "I've been going to visit Scott in rehab and I know nothing's gonna change over night but I'm really proud of him for taking this step and I'm here to support him in any way that I can."
She tells Kim, "He kept saying, 'Thank you for coming.'"
"Well that was nice," Kim says.
"It was good I'm glad I went and didn't wait," Kourtney explains. "Because mom was like, 'You gotta live in the moment and go.' And who knows what next week will bring, so it was good."
4. Kylie Jenner Cries Over Tyga:
Kylie is spending time with her sisters when they start talking about Kendall's birthday party. When Tyga's name is brought up, Kylie reveals that she wants to "disinvite" him from the party.
"Is Tyga coming?" Kourtney asks.
"I kinda wanna disinvite him because I just want it to be a friend thing," Kylie says.
"Um I don't really think that's gonna go over well," Kourtney tells Kylie.
"And because I invited him personally, it's not like you invited him," Kendall says.
"Who?" Khloe asks.
"Tyga," Kendall tells Khloe.
"You guys are fighting?" Khloe asks Kylie.
"No, I'm just over it," Kylie explains.
"Over Tyga?" Khloe asks.
Kendall then says, "Tonight I am celebrating my 20th birthday and I invited Tyga before Kylie and Tyga had their issue. Kylie's always extremely vague when there's stuff going on with Tyga, she's doesn't really open up to me at least, so I don't know I guess we'll see what happens."
A little later, Kylie gets emotional and breaks down in tears. She walks away from her sisters and Kourtney follows her to see what's wrong.
"Kyles? What happened?" Kourtney asks. "Did you get in a fight?"
"I just like don't know what to do about T," Kylie says. "He just called me and I'm just having issues with him."
Kylie then says, "It's just weird and I don't know what to do, so. Whatever I'll figure it out."
After talking with Kourtney, Kylie decides to leave.

Kylie shows up late to Kendall's birthday party and admits she's "distracted."
She explains, "I'm kinda distracted today because all I can think about is Tyga. I know Kendall already invited T, I just hope that we can make it through the night without drama."
Khloe then says, "Kylie and Tyga broke up or got into a fight I have no idea why. It's definitely awkward to have Kylie and Tyga here so we're all just like... watching."
But when Kylie and Tyga end up seeing each other at the party, they make up and all is well.
"I totally knew they'd be fine when they saw each other, I totally knew they'd get back together," Kendall says. "That's just what happens, it is what it is."

"I have only been here for about 30 minutes and I have probably been asked about Lamar 40 times," Khloe says. "And with every person who asks me about Lamar I feel like I need a glass of champagne. So..."
Khloe then is able to have a good time and enjoy the party with her family! She even cuts off Kris' when she's trying to give a speech, which Kourtney loved.
"Khloe you're the f--king shit!" Kourtney yells.
Kourtney then says, "I was happy to see Khloe just like having the best time and in her element. The old Khloe was back, she deserves to have a fun night."
